What are you, a retard? Even my 5 year old sister knew the answer to this. Hot air is lighter than cold air, thus the balloon with hot air rises higher than the cold air around it.

∙ 12y agoIf there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
Hot air rises. As the air in the hot air balloon is made hotter than the surrounding air it rises.
Because the fire or heating device heats the air in the top section ( the actual balloon ) and hot air rises... so the hot air trapped in the balloon makes the balloon rise :)
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.

The upthrust exerted by surrounding air on the balloon.

if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.

Hot air makes a hot air balloon rise because hot air is less dense than the cooler air around it, so the hot air balloon floats on the cooler air around it.
The hot air, inside of it is very light and makes the balloon rise up.
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
The heating of the air through the use of a burner is what makes balloons rise.
